a phrase that describes the quantity of pixels in a camera sensor or on a display (specifically in a digital image). More resolution translates into more pixels, and more pixels enable the presentation of more visual data (resulting in greater clarity and more detail).
STANDARD DISPLAY RESOLUTION SIZES
The most common method used in the industry to describe screen resolution is to list the number of pixels that make up the two sides of the display rectangle.
A NUMBER OF STANDARDS CURRENTLY EXIST WHEN IT COMES TO DISPLAY RESOLUTIONS:
|Name(s)||Resolution in pixels|
|High Definition (HD)||1280 x 720|
|Full HD, FHD||1920 x 1080|
|2K, Quad HD, QHD||2560 x 1440|
|4K, Ultra HD||3840 x 2160|
Standard display sizes compared
The first iPhone had a screen resolution of 320 by 480 pixels when it was introduced in 2007.
A range of smartphone screen resolutions compared
The physical dimensions of the display, camera sensor, or picture are unrelated to resolution. For instance, two screens with the same resolution may differ in terms of their physical size. The significance of the other quantity, pixel density, which is expressed in pixels per inch (ppi). The image presented by a smaller panel should be crisper and more detailed since it will have more pixels per inch at the same resolution (although graphics will be physically smaller).
